Microsoft announced another pack of promised downloadable content following the release of Ensemble Studios’ swan song, Halo Wars. The Xbox 360 exclusive strategy title gains four new maps in the Historical Battle Map Pack which “highlight key turning points in the epic war between the UNSC and Covenant forces.”

Included are Blood River, a one-on-one map with “a treacherous natural chokepoint;” Barrens, a battlefield set among Flood dangers; Memorial Basin, a two-on-two map set “in one of the bloodiest battles in Halo history;” and Glacial Ravine, pitting two teams of three against each other across “a narrow corridor flanked by energy walls.”

The pack is available now in the add-ons section of the Xbox Live Games Marketplace for 800 Microsoft Points ($10). No word on whether the map pack will make it into the rotation on Korean pro gaming TV.
